CI Behavior Inconsistency

[bvanjoi]

Describe the bug

The test harness exhibits contradictory results across configurations:

• ​With cargo test -p swc_ecma_parser --test test262 --features verify: falsely passes despite underlying issues.

• With cargo test -p swc_ecma_parser --test test262 and remove #[cfg(feature = "verify")]: Correctly fails, revealing cases where invalid parses erroneously succeed.

For instance, the test file 08bafe059b17ac92.js contains code that incorrectly passes validation: the parser successfully processes syntax that should trigger failures according to the test specifications

It's because of

swc/crates/swc_ecma_parser/tests/errors.rs

Line 66 in b4b3aff

#[cfg(feature = "verify")]

It was intended behavior, but feel free to fix it in an ideal way (in your opinion) if you want to 👍
